NEAR-FIELD TRANSDUCER WITH ENLARGED REGION, PEG REGION, AND HEAT SINK REGION

摘要

A near-field transducer includes an enlarged region having a top side adjacent to a magnetic pole, a base side opposite the top side, and a circumference that extends from proximal to a media-facing surface to distal to a media-facing surface. The near-field transducer includes a peg region in contact with a region of the bas side of the enlarged region, the peg region extending from the enlarged region towards the media-facing surface. The near-field transducer also includes a heat sink region having a contact side, a base side, and a circumference that extends from proximal to the media-facing surface to distal from the media-facing surface. The contact side of the heat sink region is in thermal contact with both the peg region and at least a region of the base side of the enlarged region.

1. An apparatus, comprising:
a near-field transducer of a heat-assisted magnetic recording slider comprising:
a peg region formed from plasmonic material;an enlarged region formed from plasmonic material and having a top side configured to contact a magnetic pole of the slider, a base side opposite the top side, and a circumference that extends from proximal an air bearing surface (ABS) of the slider to distal the ABS; anda heat sink region having a contact side, a base side, and a circumference that extends from proximal the ABS to distal the ABS, wherein the contact side of the heat sink region is in physical contact with at least a region of the base side of the enlarged region, and the heat sink region is formed from plasmonic material and configured to enhance coupling efficiency of the near-field transducer; wherein the circumference of the enlarged region is offset from the circumference of the heat sink region.
